For starters, the OLED technology used to make the curved screen is ultra-thin, and it is supposed to be very durable. This allows Samsung to build a small phone -- just 0.31 inches thick -- that will hopefully keep working even when users drop it.

Additionally, the curved screen on the Galaxy Round should make it slightly nicer to hold, with the curve fitting into consumers' hands when they hold it up.

There's also the "Roll Effect," a new feature by Samsung that can be seen in the video below.

Roll Effect lets a user tilt the device toward him or her by pushing down on one of its edges to angle the screen in their direction. When the phone recognizes this action, it automatically lights up the screen and displays information, such as the time and date.

Samsung has not announced any plans to bring the Galaxy Round and its 5.7-inch-screen to the U.S. In South Korea, it will be available for more than $1,013.
